Abstract

Titanium dioxide (TiO2)-based photocatalysis has attracted much attention, and TiO2 is extensively used as a semiconductor in photocatalysis due to its excellent and stable UV light-driven photocatalytic activity. However, owing to the introduction of electron and hole recombination centers in the TiO2, most reported modifications such as impurity doping, noble metal loading, and dye sensitization on TiO2 only have a limited role in promoting its solar light activity. The rapid development of graphene brings a new breakthrough in the field of photocatalysis. In this chapter, we will introduce the recent progress of TiO2/graphene composite application in photocatalysis and focus on the preparation, characterization, and application of two-/three-dimensional TiO2/graphene composites in photocatalysis. Finally, we will give a prospective of graphene-based materials in the photocatalysis especially for their industrial application in dealing with the environmental purification.
